Be it known that we, GEORGE YOUNG, residing at Winton, and FRANK PEARN, residing at Gorton, near Manchester, in the county of Lancaster, England, subjects of the Queen of Great Britain, have invented certain new and useful Improvements in Apparatus for Bleaching and Dyeing, (for which we have obtained Letters Patent in England, dated 1o January 22, 1890, No. 1,157; in France, dated January 23, 1891, No. 210,970; in Belgium, dated February 18, 1891, No. 93,799; in Italy, dated February 18, 1891, No. 133, Vol. 60; in Spain and Oolonies, dated August 13, 1891, No.

I5 11,992; in Austria-Hungary, dated September 21, 1891, and in Brazil, dated November 2l, 1890, No. 995;) and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable zo others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or gures of reference marked thereon, which form a part of this specification.

The invention relates to apparatus for dyeing and bleaching cotton, wool, silk, and other fibrous materials in the raw or in the manufactured or partly-manufactured state; and it has for its object the provision of means 3o whereby the operation ot' dyeing or bleaching may be effectually and expeditiously as well as economically performed.

To these ends the invention consists in the' k 4o tion, the treatin g-chamber being shown below the level of the liquid in the vat in said Fig. 3. Figs. 2 and 4 are top plan views of Figs. 1 and 3, respectively. Fig. et is a vertical transverse section of the valve-casing hl, taken centrally through one of the valve-chambers and its valve. Fig. 4b is a detail sectional view illustrating the exhaust-valve for the chamber f. Fig. 5 is a sectional view of the slide-valve employed in conjunction with the receiving-chambers and a suitable exhaust ap- 5o paratus. Figs. 6 and 7 show a three-way cock connected with the treating-chamber by a face view and a sectional view, respectively. Fig.

8 is a section taken on line A B of Fig. 3. Fig.

9 is a plan view of a cop-supporting plate or 55 table. Fig. 10 is a vertical section, and Fig.

11 a sectional elevation, of a cop and its spindle, illustrating different modes of seating the same iiuid-tightin the cop-plate. Fig. 12 is a view similar to Fig. 10, illustrating the mode 6o of seating a yarn spool or cylinder in its supporting plate or table; and Figs. 13 and 14. are like Views of supports'for yarn in the hank and for felthats, respectively, illustrating the mode of connecting them Huid-tight with their support or table.

Like symbols indicate like parts wherever such may occur in the figures of drawings just described.

The essential elements of apparatus com- 7o prise a chamber 7L, in which the fibrous materials are treated, and hereinafter called the treating-chamber; a vat, tank, or reservoir a, that contains the bleaching or dye liquor, and hereinafter called the vatg7 and two 75 vessels, tanks, or chambers b and f, into which the liquor from the vat or steam, air, or gas is or may be drawn, and hereinafter called the main and auxiliary receiving-chambers, respectively, and in combination there- 8o with of a suction apparatus whereby the liquor in the vat may be forced into the treating-chamber through the fibrous material therein and returned to the vat, or whereby the said chamber may be exhausted and 8 5 steam, air, or gas drawn through the material treated, as may be required in the operations of dyeing or bleaching. The vat a, may be of any suitable construction and appropriate material, preferably of wood, and in 9o practice is ormay be provided with a suitable exhaust valve or cock. (Not shown.)

Referring now more particularly to Figs. l 2, 4, 4b, 5, G, and 7, the vat ci, for the sake of economy, convenience, and compactness, serves as a support for the treating-chamber h, as well as for the main and auxiliary receiving-chambers b and f, said main receiving-chamber being preferably cylindrical and,

4like the vat, constructed of wood, and it is closed at its upper and lower ends. To the lower end or bottom of the chamber b is connected a pipe c, that has at its lower end a recessed flange 1X,in which is seated a flanged extension 2 of a valve-casing 3, that is connected with a pipe c, seated on the bottom of vat a and connected with a passage c9 of a valve-casing hl, hereinafter to be described. The valve-casing 3, as shown, is made flaring upwardly and has `ports c in its top surrounding the extension 2, adapted to be closed by a disk valve c2, loose on extension 2 and limited in its movements thereon by a stopcollar c3. 'lhe auxiliary receiving-chamber f, of less capacity than chamber b, is also closed at top and bottom and provided at the foot with a mushroom or other suitable valve f3, as more clearly shown in Fig. 4b, opening outwardly to discharge liquor drawn into the chamber back into vat a. A pipe f2 extends into chamber f,one end of said pipe reaching nearly to the upper end of the chamber and carrying at said end a bell-shaped hood f5, the sides of which are preferably perforated, so that when a liquid and a gaseous fluid are drawn into chamber f through pipe f2 it will strike the hood and be more or less sprayed, thereby more effectually separating the gaseous fluid from the liquid drawn in. The other end of the pipe is connected with a passage f* of the valve-casing k7, above referred to and presently to be described.

Near the upper end of the main receivingchamber b is secured a casing E for a slidevalve e3, in which are formed two cavities e7 e, and the casing E is provided with two passages c and e', respectively connected by pipes bf with the upper end of the main and auxiliary receiving-chambers l) and f and with a porte2, connected with a suction apparatus or pum p, which we have deemed unnecessary to illustrate in the drawings, since any -appropriate apparatus of this character may be used. The chamber in which the slidevalve e3 works is closed by a cover es, in which are formed openings or ports e9 to admit air freely to said chamber, and it will be understood that the valve and its stem e do not work duid-tight in the said chamber; but said valve is adapted to work fluid-tight on its bearings, so as to hermetically close the ports e4 e5 of passages e and e', respectively, and the exhaust-port e of passage e2. In Fig. `5 we have shown the valve in its middle position, all the ports being closed, and it is obvious that when the valve is moved in one or the other direction either the port e4 or the port e5 will be uncovered and communication established between the pump and either the main or auxiliary receiving-chamber, according to the position of the valve relatively to the said ports. The valve-stem cX is pivotally connected with a two-armed lever g, fulcrumed at g to the main receiving-chamber b, one arm of the, lever carrying a weight g3, that counterbalances the slide-valve e3 and lever connections, the other arm of said lever being connected through the medium of a rod g2 with one arm of a two-armed lever Z, pivoted on a shaft Z', the other arm of which lever has a handle ZX and a sector or segment l, from which project two pins Z2 for purposes hereinafter to be described. Although we prefer under certain circumstances to secure the segment to-or form the same on the lever, yet it will be understood that said segment may form a part of a separate one-armed lever secured to shaft l. By means of this lever Z the slide-valve is actuated, as will be readily understood. The treating-chamber h, as hereinbefore stated, is also mounted on the vat, and consists of a casing of preferably cylindrical form, or substantially so, the lower part h having the formof a truncated cone, the smaller end of which extends into the vat a. The lower part h6 of the treating-vessel has an interior annular seat or shoulder formed around its upper wider end, upon which are seated radial arms hs, extending from a valvecasing 7i?, between which arms passages hf are formed, through which the liquor in the vat has free access tothe upper portion of the treating-chamber 7L whenever a partial vacuum is formed therein. The upper end of the valve-casing is made fiaring outwardly and has an annular groove for the reception of a rubber or other suitable packing gasket or ring j', upon which seats the table or plate j, that supports the fibrous material to be treated and that will be more particularly referred to hereinafter. The valve-casing h has an axial passage hx, that places the chamber d below the table j in communication with a chamber c8 in the valve-casing below the valve-ports therein and with the pipes c4 f2 through ports c7, that connect the Valvechamber above the Valves therein with the passages ci f4, respectively, to which the pipes c4 and fz are connected, c5 f being the valves that control the ports referred to, and they IOO IIO

.able plates c6 f7, that serve as covers for the valve-chamber and as a means for introducing the valves or having access thereto when this becomes necessary from any cause.

Around the upper inner end of the treating-chamber h is formed an annular channel or passage h', the inner wall of which is perforated, and to said channel is connected, through the medium of an elbow-pipe hm, Fig. 2, the steam or gas branch 7a3 of a threeway valve or cock 7c, Figs. 6 and 7, the branch 7c' of which is connected with a steam or gas supply, while the branch k2 is open to the at- Inosphere. The plug 7a4 has a single port kx leading to the axial bore thereof, and said plug may be adjusted so that either branch k or k2 is broughtv into communication with the annular channel h through the bore of the plug and the branch 7c3, whereby steam or a gas or air may be drawn into said channel, thence into the treating-chamber, and through the fibrous material into the auxiliary chamber f. On the square 105 of the valveplug 704 is secured a disk los, that has a tubular hub on which is tted a second disk that forms part of a lever k7, so as to allow the disk of the latter to move freely around the hub ofthe disk k6, which is fast on the square of -the valve-plug. In the discoidal portion of the lever k7 is formed a slot kS,-concentric with the axis of the valve-plug h4, and through said slot extends a set-screw 7.49, that is screwed into the disk k6. By slackening this set-screw the valve-plug can be turned backward and forward, and by tightening the same the plug can be turned either way by means of the lever k7. As there is only one port kx inthe valve-plug and as the lever can be moved through an arc of sixty degrees only, it opens and closes the steam or gas branch only and keeps closed the air branch, or vice versa, according to the adjustment of the plug for either fluid-that is to say, according as the fibrous material is to be subjected to the action of steam or a gas in dyeing or bleaching or to the action of air, or both, alternately.

By means of the described construction of three-way valves k goods may be treated either with steam or a gas when the plug is in one position or with air when the plug is adjusted to a different position. The lever k7 projects into the path of the pins Z2 on the segment Z6 of lever Z, so that Whenever the slide-valve is actuated the plug of the valve 7c will be automatically positioned.

The treating-chamber h is closed at top by a cover h3, hinged to one side of the chamber and seating 011 a rubber or other packing h5 to form a tight joint. This cover may, however, be dispensed with when the apparatus is used for dyeing or bleaching fibrous materials without subjecting the same to the action of steam or other gaseous fluid, as will be readily understood.

The material to'be treated is supported terchangeably in the treating-chamber 7L.

Various means for securing the material to as well as various constructions of tables are shown in Figs. 9 to 13, inclusive. Fig. 9 shows a table for the support of fibrous materials in the cops, said table having a number of perforations for the tubular skewers or spindles t of the cops t, which must be seated fluidtight in their bearings or perforations in the table j. In Figs. 10 and ll'the cop has a tubular tapering skewer t closed at its upper end or point and open at its lower end and provided with slots or openings along the tubular portion that contains the windings. The lower end of the skewer carries a washer 252, that seats on a rubberor other packing t3, arranged in' an annular recess formed around the bearing in the table j, a boss t being formed around said bearing on the under side of the table, whereby a more extended bearing for the skewer is provided.

In Fig. 12 the core for the bobbin consists of a cylindrical barrel having inv each end a wooden axially-perforated plug t5, the lower plug seating Huid-tight in its bearing in the table j. In Fig. 13 we have shown a suitable arrangement for supporting a fabric to be dyed or bleached, the table having a single axial bearing js, on which is fitted a central perforated barrel or cylinder t4, the perforations at the lower end registering with corresponding perforations in the bearing js of tablej. The central cylinder is closed at top and has a T-handle j2 secured thereto, a like handle being secured to the table j, (shown in Fig. 9,) by means of which they may be lifted into and out of the receivingchamber. The central cylinder t4, Fig. 13, is surrounded by an outer open-ended cylinder t7, and both cylinders are seated on a detachable bottom t", between which and the table j is interposed a packing t3, applied around the axial-bearing g7'3 to form a tight joint, the outer casing being open at top and having perforations in its sides to admit of free access of the liquor to the cloth wound on the central cylinder.

In Fig. 14 we have shown a table for the support of felt-hat forms u. These are stacked on a support tu, seated on a disk t8, that has an axial opening fitting around a bearing js, formed around a central opening in the table j, said disk 158 seating, also, on an intervening packing-ring t3. The disk has vertical arms t9, to which is pivoted a bail or yoke-handle tx.

When the goods are to be treated in a closed chamber, the handles j2, Figs. 9 and 13, are tubular and open at both ends, so that the air in the chamber may be exhausted therefrom as the liquid is drawn in, (see, also, Fig. 1,) the lower open end of the handle communicating with the central opening in the table j and the chamber d and axial passage hx of the valve-casing 71,7. This may, however, also be accomplished by connecting a pipe with the said exhaust-passage hx or the chamber d above the same, said pipe extending to the upper portion of the treating-chamber 7L or to a point above the highest possible level of the liquid therein, as will be readily understood.

In the apparatus described and shown in Fig. 1 the treating-chamber 7L is located above the highest possible level-say, for instance, above the level y y-of the liquor in the vat a. This, however, is not absolutely necessary, as said chamber may be located below said IOO IIO

level, or substantially so, as shown in Fig. 2, which `modification we will now describe. In either construction of apparatus, however,l the main receiving-chamber `should be of a capacity about equal to thatof the vat, so that the greater portion of the contents thereof may be exhausted into said chamber, while the auxiliary receiving-chamberis of such a capacityasto receive any liquid that maybe drawn into the same withthe air, steam, or a gas drawn through the material 'under treatment.

In themodication shown in Fig. 2 no provisions are madefory subjecting the material treated to the action of steam or a gas. Hence the treating-chamber h is open at top to admit air freely thereto, and near its bottom it is provided with an annular Aflange or seat,in the upper face of whichis` formed a groove for the receptionof a rubber packing-ring j', upon which seats the table j, said table being further supported by an open-workstool or bracketstoform4 the exhaust-chamber dbelow the' table, the same 'as in' the apparatus described 'in reference toFig; 1.l The treat` ing-chamber h (has secured to its bottom a pipe fr, on the lower end of which is arranged avalve-casing C, containing the two mushroom-valvesf6 c5, said pipe 1^ leading to a chamber below the ivalves, while the chamber above saidyvalves is connected with the pipe c4 in communicationwiththe main `receivingchamber b and withl thepipef2 in the auxiliaryreceiving-chamber f through the mediumof a pipe f2, that is in thisL construction arranged outside of the vat, as shown in dotted lines. The auxiliary receiving-chamber, instead of being provided with a mushroomvalve, basi a Adepending pipe, at the foot of whichis arranged a valve-casing, in which is seateda puppet-valvef23, whose stem is guided in a suitable yoke-bearing, as shown. The said chamber above thevalves f6 c5 hasopenings in its roof normally closed by two covers f7 c6, forpurposesabove described, in respect of the like valves shown in Fig. l, and from said platesprojects a foot or lug that limits the movement of the Valves from their seats.

The treating-chamber h above table j can be placed in communication with a pipe h, that opens into the vat @,through the medium of a sluice-valveo2 in a valve-box 1o in branch p, to which i, the pipe h6 is connected. The spindle p4 of the valve is guided. in and eX- tends through a tubular bearing p5 and has its -upper end'pivoted to one arm p6 of a bellcrank or angle lever that is fulcrumed on a stud p7, secured to a bracket projecting from the tubular bearing p5. The arm p8 of the angle-lever carries a weight p9, so that when saidl arm passes beyond a vertical intersecting the'lever-fulcrnm the weight will carry the lever-arm over by gravity when said lever is moved in oneor the other direction to open or close the valve p2. The necessary movements are imparted to the lever-arm p8 either by hand, said arm terminating in a handle, or

from the hand-lever l, that operates the slided valve, through `the following instrumentalities: On` the shaft Z of lever lis secured a radial arm q', to which` is pivoted one end of a connecting-rod q, whose opposite end( is slotted for the reception of a pin px, projecting from the lever-arm p8, so that the slide-valve @Tand the sluice-,valve p2 are moved successively. On the fulcrum-stud of the lever 196198 1s secured a radial arm Q21, thathas a setscrew q, working' in a `threaded opening formed in the outer end of said arm, on which set-screw the arm p8 of the lever has bearing, whereby the lift yor extent of opening of the valve p2 may be adjusted. Inasmuch as the treating-chamber h isopen, the cop-supporting table has a solid handle j instead of a tubular one, as described in` reference to Fig. 1.

In the treatment of cloth or felt hats the treating-chamber h in either construction of machine may be of such diameter as to accommodate a single table, or it may be made sutciently large to accommodate a plurality of such tables with their supports for the cloth or hats described in reference to Figs. 13 and 14. In dyeing or bleaching we have found it more economical and expeditious to employ a separate machine for each operation. In dyeing, for instance, one machine may be used for mordanting and another for dyeing and treating the dyed ymaterial with air or steam or a gas. In bleaching one machine may be used for cleansing or scouring by subj ecting the material alternately to the action of a solution of caustic soda, for instance, and to that of steam. Another machine may be used for washing andlanother for treating the material with a bleaching agent, either liquid or gaseous. In this manner the operations may be carried out successively in their proper order by a simple transfer of the tables j with the material thereon from the treating-chamber of one machine to that of another.

With our improved machines ,the liquor used can be readily filtered, if desired, by simply substituting a perforated plate for the table j and securing thereto a filter-cloth. The liquor may then be drawn through said lter-cloth and into the receiving-chamber b, the sediments or solid matter being removed from the filter before any material is treated, the liquor being returned to the vat after filtration. Of course such ltration may beeffected ina special apparatus.

The operation of our machine may be brieily described as follows, referring to Fig. 1: If the liquor or dye used is to be rst filtered, it is introduced into the vat, and instead of the table j a perforated plate provided with filtercloth is substituted therefor, the pump (not shown) is started, and the slide-valve set so as to establish communication between pipe b and the valve ports and passage e, e, and e, respectively, whereby a partial vacuum is formed in the main `receiving-chamber b andv IIO in the seating-chamber h through pipe c4, passage o9, the chamber above valve c5, which moves oif its seat, the chamber below said valve, the axial passage hX, and the chamber d below the filter-plate. The liquid in the vat a is thereby lifted and drawn through the iilter and by the way described through the pipe c4 into receiving-chamber b, the valve c2, interposed in pipes c4 c, closing under the action of such partial vacuum. Vhen all the liquid has been filtered and the solid matter and filter-plate removed, the slide-valve is set to admit air to chamber b, such air having free access to the slide-valve casing, as hereinbefore described, when the partial vacuum in said chamber will be destroyed and the liquid will at once iow down into pipe c4, thereby lifting the valve c2 and iiowing back into vat a. The same operation takes place when the liquid is drawn through the material to be treated, the tablej with such material being placed in the treating-cl1amberh,the slide-valvebein g operated by means of the lever Z. After the material has been subjected to the action of the liquid for a suiiicient length of time and it is desired to treat the same with airor steam the slide-valve c7 is set to establish communication between the slide-valve ports and passage en, c5, and e', respectively, and the pipe f of the auxiliary chamberf, whereby a partial vacuum is produced in said chamber and in the treating-chamber through pipe f2, passage f4, passage c7 above valve f6, which opens (under partial vacuum) the suction-chamber oS below the valve, axial passage dx, chamber d below table j, and through the material. As the slide-valve is moved into the position referred to the cock 7c, through the instrumentalities described, is also positioned to admit steam, for instance, from branch k into the closed treatin g-chamber h through the annular passage h. The steam is thus drawn into the auxiliary chamber together with any liquid that may be drawn from the material or may be in the valve-casing, such liquid being projected against the under side of the hood f5 for purposes already stated, and as soon as the vacuum in chamber f is destroyed by shifting the slide-valve the liquid therein will ow back into the vat a, the mushroomvalve f5, which was held to its seat under the action of the partial vacuum, opening under the pressure of the liquid.

The general operation of the apparatus shown in Fig. 2 is substantially the same, ex-

cept that no provision is made for the use of steam or a gas, except air, and when airv is to be drawn through the material in the open treating-chamber h, after having been subj ected to the action of the liquid in the vat, the slide-valve is set to establish communication between the suction -passage and the auxiliary receiving-vessel f, the sluice-valve p2 being closed. A partial vacuum will be formed in chamber f, under which the valve f6 will move off its seat, and the ambient air in the treating-chamber h will be drawn through the material. In this form of 'apparatus the setting of the slide-valve to establish4 communication between the passage and the main receiving-chamber b will also open the sluice-valve p2, the liquor in vat a being drawn through pipe h6 into valve-casing, thence through valve-port into chamber p3, Fig. 6, whence it will rise into the treatingchamber 71,. W`hen, on the contrary, the slidevalve is set to establish communication with the auxiliary receiving-vesselV f, the sluicevalve 192 is closed through the instrumentalities above described.

The time during which the material is to be subjected to the action of the liquor in the vat ct may be determined by a graduated scale applied Within the vat, indicating various levels of the liquid, the quantity of liquid drawn through the material determining the time.

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is-
